Kelly Clarkson Joins Trisha Yearwood Onstage In Chicago For ‘Prizefighter’ [VIDEO]

Garth Brooks kicked off his world tour last week in Chicago along with his wife, Trisha Yearwood.  In addition to having a few megastars in the audience, they brought Kelly Clarkson out, much to Garth's "surprise!"

Trisha has a new song out called Prizefighter which features the amazing vocal talents of Kelly Clarkson.  She joined Trisha on stage to sing the tune live.  All I can say is they sound amazing together!
